' Application filed August 12, 1918, Serial No. 249,431. Rcnewed'March 25, 1921. Serial No. 455,434.

To all whom it may concern:

Be it known that I Gaza HoRvA'rH, a citizen of the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain'new and. useful Improvements in Hadiator Construction, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to radiator construction and more particularly to the grid or core thereof and to such an arrangement and construction of the same as to provide a very efficient cooling arrangement, while at the same time the structure is capable of withstanding the rear shock, vibration and the like so that it is particularly adapted for use on heavy service vehicles running on hard tires and over rough grounds.

The invention consists in the matters-hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a View in elevation ofa radiator the grid of which embodies features of the invention; I

Fig. 2 is a view in detail showing a por' tion of the core or grid;

Fig. 3 is a view inside elevation of a portion of a division plate;

Fig. 4: is a view in section of the plate taken through the line of apertures thereof; and

Fig. 5 is a view in section and in enlarged detail showing the construction of the water tube of the radiator. 7

As herein shown, an upper header 1 and lower header 2 with sides 3 inclose a grid shown generally at 4, the water tubes 5 of which connect the upper and lower headers.

Each tube 5 is formed of a pair of oppositely crimped and corrugated plates 6 and 7, having oflset marginal portions 8 which are sweat soldered together, the separate inner portions forming a tortuous passage for the water. At the crest of each corrugation, the sheet material of which the tube is made is outbent and folded on itself to form a series of spacing members 9 which are arranged to hold the tubes in proper spaced relation to an intermediate spacing plate 10.

- The assembly of plates 6 and 7 provides a unit in which the tube is of zig-zag formation with the members 9 projecting from the apex of the angles of the zigzag.

As herein shown the spacing plates 10 are corrugated to correspond in general contour to. the tubes, and are perforated along the walls of each corrugation as indicated at 11. Furthermore the connecting portions 12 and 13 between the several apertures are offset angularly or crimped out to form baffles whereby air passing horizontally through the radiator as the latter is moved forward by the motion of the machine on which it is situated, is caused to be deflected against the walls of the adjacent water tube.

As will be seen, the particular arrangement of units and spacing plates is such that in the assembly the spacing members 9 of one unit project beyond: a plane which meets the ends of the spacing members of the opposed unit, with" both sets of members in contact with the spacing plate 10, the latter having itsdimensions such that there is produced this somewhat overlying relation between adjacent members 9. This provides a construction of a plurality of cells between adjacent tubes to permit of maximum access of air to the sides of the tube and at the same time permits of the use of a comparatively large number of tubes within a given area. And this is further enhanced by reason of the presence of the particular configurations of the spacing plates 10 the openings 1 being arranged in the direction of length of a wall oftho depressed portion of the plates, with the material between openings arranged to defleet the air passing through the cells, so that there is a tendency to deflect air from one side-to the other of the plates, and thus aid in tending to direct the air to the tube surfaces.

As a result of this construction a very rigid grid is obtained which is very effective in cooling on account of the impingement of the air current against the walls of the tubes, the cross-sectional area of the latter being very small in proportion to the surface exposed to the air. Furthermore because of the minimum number of joints, the

liability to leakage from the vibrations and shocks due to heavy road use, is minimized, while the reinforcing and spacing plates con-tribute to the stiffness of the structure. Obviously, changes the details of c0I1- struction may be made without departing from the spirit of my invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is 1. In radiator construction, a core assem bly comprising a plurality of tube units each having a plurality of spacing elements projecting alternately in opposite directions, each unit having a zig-zag formation in the direction of fluid flow with the spacing men1- bers positioned at the apices of the angles, and a spacing plate positioned between units and having a configuration to extend substantially parallel to the units, said plate having dimensions to permit the spacing members of one unit to project beyond the extremes of the opposing members of the adjacent unit, both sets of members contacting with the interposed spacing plate, said assembly providing air passages on opposite sides of the plate, said plate having a configuration to permit movement of air from one space to another.

2. In radiator construction, a core assembly comprising a plurality of tube units each having a plurality of spacing elements projecting alternately in opposite directions, each unit having a zig-zag formation in the dirction of fluid flow with the spacing members positioned at the apices of the angles,

. and a spacing plate positionedbetween units,

the spacing members of one unit projecting beyond a'plane which meets the ends of the spacing members of the opposed unit, with both sets of membersin contact with the spacing plate, said assembly providing air passages on opposite sides of the plate, said plate having a configuration to permit movement oi? air from one space to another.

8. ln radiator construction, a core assembly comprising a plurality of tube units each having a plurality of spacing elements pro jecting alternately in opposite directions,

each unit having a zig-zag formation in the direction of fluid flow with the spacing members positioned at the apices of the angles, and a spacing plate positioned between adj acent units, said plate having a zig-zag formation corresponding to that of the unit body, and positioned to locate the spacing members of the units at the bottoms of the plate depressions, with the depressions of a depth suilicient to permit the members of one unit to project beyond a plane which meets the ends of the members of the opposed unit, said assembly providing air passages on opposite sides of the plate, said plate having a configuration to permit movement of air from one space to another.

4. A core assembly of the type of claim 3 characterized in that the spacing plate is provided with a plurality of spaced open- 'igs alined in the directioniof length of a wall of a plate depressed portion.

5. A core assembly of the type of claim 3 characterized in that the spacing plate is provided with a plurality of spaced openings alined in the direction of length of a wall of a plate depressed portion, with the plate material between adjacent openings bent to deflect passing air from one side to the other of the plate.

6. A core assembly of the type of claim 3 characterized in that the spacing plate is provided with ajplurality of spaced open ings alined in the direction of length of a wall of a plate depressed portion, the plate material between adjacent openings formed to produce a portion projected relative to the wall plane, with the projecting portion located at the rear of an opening to provide air deflection from one side of the plate to i the other.

7. A core assembly of the type of claim 3 characterized in that thespacing plate is provided with a plurality of spaced openings alined in the direction of length of a wall of a plate depressed portion, the plate material between adjacent openings formed to produce a portion projected relative to the wall plane, with the projecting portion located at the rear of an opening,and with successive projecting'portions extending to different sides of the wall. plane, whereby air will be deflected from one side to the other of the plate.

In testimony whereof I afiix my signature in the presence of two Witnesses.
